CORPORATION OF PENNSYLVANIA PLATFORM Application nled December 12, 1929.vSerial llc. 413,527.

,OurV invention relates to certain improvements in platforms used forsupporting merchandise in warehouses and factories.

The object of our'invention is to construct a platform partly of sheetmetal and partly of wood and to make a comparatively light structurewhich will be of suliicient strength to c'arr the load for which it isintended.

The invention also relates to the construction of the body of theplatform.

In the accompanying drawings:

Fig. 1 is a plan view of our improved platform;

Fig. 2 is a side view;

Vu Fig. 3 is a sectional view on the line 3 3,

F ig. 4 is a sectional view on the line 44,

i 1' Fig. ,5 is a sectional view on the line 5-5,

a0 Fig. 1;

Figs. 6 and 7 illustrate modifications our invention; and A Fig. 8 is asectional view illustratin another modification, in which one o thestringers is located alt'the end of the platform.

Referring tothe drawings, 1 is the body of the platform and 2 are thesupporting legs, which elevate the platform to sutlcient distance abovethe iioor so that a carrying truck can be inserted betweenthe legs andunder the platform.

The body portion 1 has a sheet metal floor 3, flanged at each end as ati and at each side, the flan e being preferably inturned as at 5 so asto gorm a channel on all -four sides of the truck.

6-6a are wooden stringers which extend from one side of the truck to theother, and

the ends of these stringers are supported by the inturned flanges of thefloor plate. The

through which pass the bolts 7. Shoes 10 of sheet metal are U-shaped inform and lit the lower portlons of thewooden stringers 6, remforcmg thestringere vat the point where the bolts 7 pass through said stringers.This reinforcin plate also acts as a chaing plate for the en s of thelegs 2.

' In Fig. 6 a reinforcing channel member 11 1s located within thechannels formed by bending the floor plate 3, and the ends of the woodenstringers are reduced to t thisvchan-l nel as shown in Fig. 6.

In Fig. 7 we have illustrated a modification which is designed for aplatform to carry heavy loads.` In this instance the flange 4a extendsfrom the plate 3a a considerable distance below the bottom lof the strinrs 6b, and the inturned portion 5a of the ange 4 bears against the edgeof the leg 2a, supporting the leg some distance from its connection withthe wooden Stringer.

In Fig. 8 we have illustrated a modification, in which one of the sidemembers of the leg 2a is secured to a stringer 6c2 on which is the shoe10, while the other Stringer 6d is located in the channel formed by thelian e 4b and inturned portion of the flange 5b o the floor plate 3b. Inthis-instance the extension of the leg is secured directly to the woodenStringer 6d, the bolt passing through the plate 7 3b, through theStringer and through aperforation inthe extension of the leg.

By the above construction, it will be seen that we are enabled to make acomparatively light platform which will support heavy weights, and to sodesign the connections between the legs and the platform that the legscan be firmly secured in position without liability of becoming loosedue to rough usage.

While we have'described the stringers as made of wood, other materialsmay be used without departing from our invention.

We claim: 'e

1. The combination in a platform, of a sheet metal plate forming thefloor of the platform flanged at the sides, the iianges being inturnedto form reinforcing channels at the sides of the platform; a series ofwooden stringers extending from one side of the rmmvma, A

platform to the other under 'the floor; U- shaped legs having extensionsat their upper edges; and bolts securing the legs'to the strmgers and tothe floor plates.

2. The combination in a platform, of a fioor plate having inturnedflanges at each side and at each end, forming reinforcing channels; apair of wooden stringers at each end of the platform extending into thechannels at the sides of the platform; legs located under the twostrlngers at each end of the platform and secured thereto and to thefloor plate; a central transverse Stringer extending from one side ofthe platform to the other and into channels at the sides of the floorplate; and means for holding the center Stringer against lateralmovement.
